I have narrowed it down now, I was going to go for a crunch but dnt think its worth it as my bxi is 2600 rms.
The powerbass is 3000rms and the IA is 1800w rms @ 1ohm but underated. so now i have to choose between 1 or the other. All I want to know is will there be a NOTICEABLE differnece in power between the PB and IA . sorry for the noob question
